GRENA ULTRA MICRO was created for distribution on soils not subject to subsequent tillage (such as grassy vineyards and orchards). The micro-pellet formulation allows natural organic nitrogen to be readily available for plant nutrition. Thanks to the fast mineralization time, GRENA ULTRA MICRO is also ideal for last-minute fertilisations. The product meets the need for agriculture with a lower environmental impact: obtainable through a significant reduction in dosages, thanks to the natural presence of amino acids and humic and fulvic acids that facilitate the assimilation of nutrients. With GRENA ULTRA MICRO, the distribution is uniform and of low visual impact, excellent with transplanters.
The presence of calcium enhances the organoleptic qualities of the vegetable tissues as well as increasing of preservability and crispness of the fruit. In vineyards, it promotes the development of regular internodes and a net increase in the final Babo grade. The presence of silicon SiO2 leads to thicker peel in fruit and more resistance to harmful insects.
